  • Publication number: 20200217821
    Abstract: A tempo-spatial evolution test system for rock breaking in deep and complex environment includes an acoustic emission sensor assembly and an acoustic emission amplifier assembly that are arranged on a rock mechanics test system. A triaxial cavity coupling bracket is arranged on an outer wall of the triaxial cavity and between two sets of acoustic emission sensor assemblies. The triaxial cavity coupling bracket includes a plate-shaped bracket, two sickle-shaped brackets, and at least three bracket bolts, which can be tightly wrapped on the outer wall of the triaxial cavity. A lateral side of the plate-shaped bracket vertically fixes two guide columns. The acoustic emission amplifier assembly is arranged between the two guide columns and is located above the plate-shaped bracket, and the acoustic emission amplifier assembly is connected to the acoustic emission sensor assembly through a signal line.

  • Publication number: 20190331566
    Abstract: A bearing system for rock mechanics test under high temperature and high pressure multi-field coupling includes a force sensor lifting seat and a jack. The force sensor lifting seat includes a connecting disk connected with the jack, a support disk, and an operation channel. A groove dented downwards is arranged on the connecting disk, the support disk is disposed in the groove and freely propped upon the connecting disk; through holes of the connecting disk and the support disk form a control operation channel; and a limiting device is arranged for preventing an MTS triaxial force sensor from disengaging from the support disk. A bolt hole of the force sensor can be aligned with a mounting hole on a solid steel column by rotating the connecting disk for convenient and accurate bolting.
